Hello friend,
Yes, you will get better quality videos using PCVR and DeoVR for PC (available on Steam) as long as you adjust the Quest debug tool encoding bitrate as minimum as 300 Mbps and maximum of 500 Mbps and set the Distortion Curvature setting to Low.
This is more in depth old but still valid post about this:
I myself was surprised by all the test results I did between the two platforms (PCVR and Standalone). We talked about this in details here:

Actually, I just ordered the Pimax Crystal Light to go full PCVR for everything from now on.
Tell me if you need any help with the setup as I still have the Quest 3 for now.
Respectfully and best regards.
